Manual: Introduction

Orion2 Redone is a new way to enjoy Master of Orion II: Battle at Antares (MOO2), the classic strategy game about leading a civilization into the stars.

Explore the galaxy, settle new worlds, pursue scientific discoveries, design fleets, and decide whether other civilizations will become allies or rivals. Each game tells a different story as your people grow from a single home world into a galactic power.

Version 2.00 keeps the rules and character of the original game while bringing together years of community fixes and thoughtful improvements. It is designed to feel familiar to returning players and welcoming to anyone discovering MOO2 for the first time. You can play on your own or share a game with friends.

Orion2 Redone does not include the original game, so you will need your own copy before you begin.
